Job description

About Capgemini

Capgemini is an AI-powered global business and technology transformation partner, delivering tangible business value. We imagine the future of organizations and make it real with AI, technology and people. With our strong heritage of nearly 60 years, we are a responsible and diverse group of over 420,000 team members in more than 50 countries. We deliver end-to-end services and solutions with our deep industry expertise and strong partner ecosystem, leveraging our capabilities across strategy, technology, design, engineering and business operations. The Group reported 2025 global revenues of €22.5 billion.

About The Role

We are looking for a Senior Backend Engineer to take End-to-End Ownership of our backend systems for a mission‑critical Regulatory Licensing Platform. You will be a key technical pillar on a lean, high‑impact product team building application processing systems within a Highly Restricted Cloud Environment.

This role demands a Systems‑First mindset. You won't just write code; you will own the entire lifecycle of your work – from architectural design, development to Day 2 operational support, comprehensive monitoring, and infrastructure stability. We need someone who can translate complex compliance requirements into stable, production‑ready reality without heavy oversight.

Responsibilities

• End-to-End Ownership & Autonomy: Own backend systems from greenfield development through to production. Navigate technical ambiguity independently, proactively identifying blockers and driving implementations to completion without needing constant direction.
• Systems-Led Backend Development: Develop resilient APIs using Node.js/Type and PostgreSQL, designed for Just-in-Time (JIT) data access. You are responsible for writing comprehensive tests and ensuring all data is encrypted at rest and in transit.
• Infrastructure Support & Proficiency: Take operational responsibility for self-hosted components (EC2, EKS). Automate patching, hardening, and recovery, and manage secure transport protocols (SFTP/SSH).
• Cloud Infrastructure & Networking: Build and maintain multi-zone logical segmentation (Edge, Integration, App, and Vault). This includes managing virtual networking (VPC), IAM policies, and secure communication patterns.
• SaaS & Service Integration: Own the integration of critical third‑party and central services (e.g., secure file‑transfer gateways and notification engines). You ensure these handshakes are reliable, automated, and strictly auditable.
• Observability & Reliability Mindset: Design and implement a robust monitoring plane (CloudWatch, etc.). Define metrics, set up distributed tracing, and configure proactive alerting to catch issues before they impact users.
• Infrastructure-as-Code (IaC): Ensure every resource is auditable and reproducible using Terraform / AWS CDK, adhering strictly to Policy-as-Code.

Requirements

• 5+ years of Backend Engineering Experience: A proven track record of building, deploying, and maintaining complex, production‑grade systems independently
• Demonstrated Independence: Proven track record of building, deploying, and maintaining complex, production‑grade systems independently.
• Cloud Infrastructure Fluency (AWS preferred): Deep, hands‑on experience with cloud-native architectures, specifically networking (VPC), identity management (IAM), and secure data patterns.
• Technical Stack Mastery: Proficiency in Node.js/Type and relational database design (PostgreSQL)
• Systems & OS Knowledge: Strong proficiency in Linux administration and container orchestration (Docker/Kubernetes). You understand the plumbing of how code runs on a server.
• Communication: Ability to explain complex technical trade‑offs to non-technical stakeholders (PMs/Designers/Business Owners) clearly and concisely.
• Collaborative and low-ego — you care about the team succeeding, not just your own ticket closing
